2. “Sharing Economy”
The "sharing economy" refers to startups that allow people to use what they already have, but not always, to make more money. Uber will allow car owners to make extra money by driving around; They get paid to conduct their car, while passengers save on hefty taxi costs.
With Airbnb, people share a room they already have in their own homes. They can earn passive income by allowing tourists to stay in that room, even though they have to make sure the place is clean.
